This is when Balloon Belly is taken to its logical conclusion. Fill a human or some body part with enough food, water, air, etc. and they will eventually burst. Of course, when this is applied to Death by Gluttony, its usually Played for Laughs. There is little actual Truth in Television to this, as, while the skin can indeed rupture, it wouldn't do so drastically in most cases. Even barring that, the internal organs you are filling (stomach, lungs, nasal area) would rupture long before the skin itself. Yet in fiction, the rupture is simply measured by the body exploding.

Can sometimes be Nausea Fuel, though in lighter works, the lack of blood and gore may counter this somewhat. Sometimes the body just pops and disappears, though sometimes, the exploding body will shoot the contents it was filled with everywhere, with the actual body parts not showing up.

Largely a Discredited Trope, as it was mostly born from an Urban Legend that eating too much would make a person explode, then evolved to other forms of humans popping from overfilling. However it is still sometimes used in works that are not going for realism.

One of Kenny's many deaths in South Park is when he explodes after eating a whole tray of effervescent tablets and drinking a glass of water. After the initial Oh Crap moment, everyone else in the room finds it hilarious.

A non-lethal version of this trope is used as the core concept of Kablamus, a villain from The Mask.
